3.7 Temperature measurement (T°)

3.7.1 Without a sensor

Set the selector switch to the "T°" position.
The temperature displayed is the instrument's internal
temperature (the INT symbol is lit), which is the same as the
ambient temperature after a sufficient thermal stabilisation time.
It can be expressed as °C or °F: the unit is chosen with the
yellow key.

3.7.2 With a sensor

1. Connect the sensor (couple K) to the clamp terminals,
complying with the polarity indicated, and put in the place
where the temperature is to be measured.
2. Set the selector switch to the "T" position. The temperature
displayed is that of the sensor (EXT symbol is lit), it can be
expressed in °C or °F: the unit is chosen with the yellow
key.

3.8.1 Blocking the display

A short press on the HOLD key freezes the display.
The display is cleared when the key is pressed for the second
time.
